Update iPhone 11 Pro to iOS 18.1

Sorry, your post is not very clear.

An iPhone 11 can run iOS 26. The most current version of which is iOS 26.2.1 and that’s the only version you can update to at this time.

Go to Settings ➜ General ➜ Software Update.

I want to update any of version ios 18. I don’t like ios 26

You cannot have what you want. If there is an update available for your iPhone 11 Pro and you click "update", your iPhone will be updated to iOS 26.2.1

So, you have two options.....do nothing and stay on iOS 16.2 or update to iOS 26.2.1

Take your pick

You cannot downgrade to iOS 18 anymore, since it is not being signed anymore.

You provided an answer to a question that was not asked. Check the original post again to see that the OP did not ask to downgrade to iOS 18.

Re: “I want to update any of version ios 18. I don’t like ios 26”

You cannot update to iOS 18. Apple no longer allows it. Even those of us who were on iOS 18 (but had phones that could run iOS 26) were kept from getting iOS 18.7.3 or iOS 18.7.4.

If you do not update to iOS 26 (or possibly its successor) by next January, iMessages and FaceTime will stop working. Updating to the version that you do not want is the only way for you (as opposed to a user of an older phone) to get the fix.

As stated above, that is not possible.

Ohh, my bad. Same answer though, OTA updating to iOS 18 is not possible either. OTA updates are also not being signed anymore.
